    For those who make up their mind based on facts. (for those who deny the findings in the report: did you read it?)

    Unmistakable signs of a warming world

    28 July 2010, Updated 29 Jul, 10:30

    Scientific evidence that our world is warming is unmistakable has been released today in the ‘2009 State of the Climate’ report, issued by US National Oceanic and Atmospheric Administration (NOAA).

    The report draws on data from 10 key climate indicators that all point to that same finding — the world is warming.

    The 10 indicators of temperature have been compiled by the Met Office Hadley Centre, drawing on the work of more than 100 scientists from more than 20 institutions. They provide, in a one place, a snapshot of our world and spell out a single conclusion that the climate is unequivocally warming.

    Relying on data from multiple sources, each indicator proved consistent with a warming world.

    Seven indicators are rising and three are declining.

    Rising indicators

    1. Air temperature over land
    2. Sea-surface temperature
    3. Marine air temperature
    4. Sea-level
    5. Ocean heat
    6. Humidity
    7. Tropospheric temperature in the ‘active-weather’ layer of the atmosphere closest to the Earth’s surface

    Declining indicators

    1. Arctic sea-ice
    2. Glaciers
    3. Spring snow cover in the northern hemisphere

    Dr Peter Stott, Met Office Head of Climate Monitoring and Attribution and contributor to the report says: “Despite the variability caused by short-term changes, the analysis conducted for this report illustrates why we are so confident the world is warming.

    “When we look at air temperature and other indicators of climate, we see highs and lows in the data from year-to-year because of natural variability. Understanding climate change requires looking at the longer-term record. When we follow decade-to-decade trends using different data sets and independent analyses from around the world, we see clear and unmistakable signs of a warming world.”

    Dr Jane Lubchenco, Under Secretary of Commerce for Oceans and Atmosphere and US NOAA Administrator, says: “For the first time, and in a single compelling comparison, the analysis brings together multiple observational records from the top of the atmosphere to the depths of the ocean.

    The records come from many institutions worldwide. They use data collected from diverse sources, including satellites, weather balloons, weather stations, ships, buoys and field surveys. These independently produced lines of evidence all point to the same conclusion: our planet is warming.”

    The report points out that people have spent thousands of years building society for one climate, and now a new one is being created — one that is warmer and more extreme.

    While year-to-year changes in temperature often reflect natural climatic variations such as El Niño/La Niña events, changes in average temperature from decade-to-decade reveal long-term trends such as global warming.

    Each of the last three decades has been much warmer than the decade before. At the time, the 1980s was the hottest decade on record. In the 1990s, every year was warmer than the average of the previous decade. The 2000s were warmer still.

    “The temperature increase of one degree Fahrenheit over the past 50 years may seem small, but it has already altered our planet,” said Deke Arndt, co-editor of the report and chief of the Climate Monitoring Branch of NOAA’s National Climatic Data Center.

    “Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common. And, as the new report tells us, there is now evidence that more than 90 percent of warming over the past 50 years has gone into our oceans.”

  • What-A-Coincidence

    The world has warmed before ... before our pollutants ... it's a cycle ... happens who knows how many thousands of years. Next debate?

  • bohm

    WAC: So you believe the earth is warming now? Do you believe it is due to human activity?

  • moshe

    And next year we could have a super volcano eruption in yellowstone, plunging the northern hemisphere into a 10 year long winter.

  • ProdigalSon

    The entire solar system is heating up. It is directly related to 2012 and the end of the Mayan Calendar.

  • garyneal

    Days and days of 100+ degree F weather around here tells the tale.

  • Bonnie_Clyde

    It's been warming up ever since the last ice age. I'm glad.

  • Bonnie_Clyde

    Check out this website. BTW, anybody remember hearing about the intense heat waves back in the 1930's?

    It is world wide heat waves we're experiencing now. The 1930s heatwaves you're referring to were in the United States.

    Also, it seems that you give out websites without carefully looking at them. Here's what I found on the second entry:

    Climate myths: They predicted globalcooling in the 1970s ...

    Update: A survey of the scientific literature has found that between 1965 and 1979, 44 scientific papers predicted warming, 20 were neutral and just 7 predicted cooling. So while predictions of cooling got more media attention, the majority of scientists were predicting warming even then.

    And immediately below on the third entry:

    Study debunks 'globalcooling' concern of '70s -

    The supposed "global cooling" consensus among scientists in the 1970s — frequently offered by global-warming skeptics as proof that climatologists can't make up their minds — is a myth, according to a survey of the scientific literature of the era.

    The '70s was an unusually cold decade. Newsweek, Time, The New York Times and National Geographic published articles at the time speculating on the causes of the unusual cold and about the possibility of a new ice age.

    But Thomas Peterson of the National Climatic Data Center surveyed dozens of peer-reviewed scientific articles from 1965 to 1979 and found that only seven supported global cooling, while 44 predicted warming. Peterson says 20 others were neutral in their assessments of climate trends.

    The study reports, "There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age.

    "A review of the literature suggests that, to the contrary, greenhouse warming even then dominated scientists' thinking about the most important forces shaping Earth's climate on human time scales."

    So what exactly are you trying to say?

    The world was even hotter long before we came along.

    Global warming is happening. It has happened before.

    We need to prepare for it, instead of endless "what if" "what if not" debates.

    Unfortunately most of the worlds governments only want to worry about votes at the next election (The chinese don't vote when they have an election)

    I hate to think that it is the poorest people in the world who will suffer the most.

    American industry has cottoned on to the idea that if they can convince everybody that GW is man-made, maybe everybody will start buying their green technology. The downside of this is that if the politicians decide it really is man-made, then we can prolly expect to see the US bombing coal fired powerstations in India when the Mississippi basin is threatened with sea inundation.
